Definitions

  • This invention relates to a surface winder with recycled mandrels and method and, more particularly, to a surface winder wherein the web is enveloped directly around the mandrel so as to develop, in effect, a "coreless" log of convolutely wound material.
  • the invention is to provide a winder which employes "free" mandrels which are pulled out of the finished log and thereafter recycled into the winding process. Recirculated mandrels have been used for a long time -- see Patent 3,148,843.
  • the main objective of the invention is to produce a wound product without separate core material. It is also desirable to have a hole in the center of the product so that a variety of dispensers can be used.
  • the hole is preferably small, in the range of .375 inches (about 10mm) to .750 inches (about 20mm), so that the rolls cut from the log are stable.
  • stable we mean that the wound structure will not collapse or unravel internally during cutting, packaging, shipping, etc. Larger holes tend to require a "fixing agent" to stabilize the area near the "core".
  • Another objective is to wind these products in a high speed, continuous manner.
  • the products are wound onto free mandrels but in a start/stop operation.
  • These winders are typically limited in production due to the need to decelerate the entire line (unwind, embosser, rewind) to zero web speed during the transfer process.
  • the numeral 10 designates generally a frame for the machine which is seen in FIG. 6 to include side frames 10a and 10b.
  • the side frames 10a and 10b rotatably support a plurality of rolls or drums for processing of a web and define essentially a winding path for the web in its travel from a parent roll (not shown) toward becoming a retail sized log of paper, other web material, foil, etc.
  • a parent roll not shown
  • a retail sized log of paper, other web material, foil, etc for additional details of winders, reference may be made to co-owned patents RE 28,353 and 4,828,195.
  • the symbol W designates a web of material which is being advanced through a path designated in part by the symbol P and which first includes travel around a perforator roll 11 which operates against an anvil (not shown) to transversely perforate the web along equally longitudinal spaced lines of transverse perforation.
  • a perforator roll 11 which operates against an anvil (not shown) to transversely perforate the web along equally longitudinal spaced lines of transverse perforation.
  • Conventionally the spacing between lines of perforation in toilet tissues may range in different parts of the world from 4 to 5 inches (100-125mm). Different spacing are employed for kitchen toweling.
  • a suitable perforator is seen in co-owned patent 2,870,840.
  • lay-on roll designated 12 which again is suitably rotatably mounted like the other rolls or drums within the frames 10a and 10b.
  • first winding drum or bedroll Positioned adjacent the lay-on roll 12 and still further in the path of travel of the web P is a first winding drum or bedroll generally designated 13.
  • a mandrel-introducing mechanism generally designated 14.
  • this is a hypocycloidal introducing mechanism of the nature shown in co-owned patent 4,856,725 which provides a gripping action on a cylindrical member.
  • the mechanism 14 functions to introduce a mandrel such as designated 15 into the nip 16 between the lay-on roll 12 and the bedroll 13.
  • a mandrel such as designated 15 into the nip 16 between the lay-on roll 12 and the bedroll 13.
  • the mandrel 15 follows a portion of the winding path P inasmuch as the mandrel and the web are now proceeding together at least partway around the periphery of the first winding drum 13.
  • the log L After the log L has been developed and a new mandrel is in the process of being wound, the log L rolls down a table 21 as indicated by the positions L', L'' and finally L'''.
  • a stripping operation is performed wherein first the mandrel 15 which has an end protruding beyond the log L''' (FIG. 6) is gripped by means of a jaw gripper 22. Between the adjacent end of the log L''' and the gripper 22, a pusher 23 is interposed.
  • the pushers 23 are carried by a conveyor mechanism generally designated 24 and operates to strip the log L''' from the mandrel 15 by moving the same axially along the mandrel 15 and onto an extended portion of the conveyor 24 (see FIG. 6).
  • FIG. 1 shows the inventive winder using a very small diameter mandrel 15.
  • the main objective of this winder is to produce a coreless roll with a very small hole in the center.
  • the bedroll 13 uses vacuum port means generally designated 26 and 27 to hold the web against the bedroll surface.
  • the vacuum port 26 is seen to include two separate arrangements of axially extending ports in the outer surface of the bedroll 13.
  • the port means 26 include a triple row of primary vacuum ports 28 and a secondary double row of vacuum ports 29.
  • the ports 29 are arranged to circumferentially flank the primary vacuum ports 28.
  • the double row of vacuum ports 27 is spaced forwardly in the direction of rotation from the first mentioned vacuum port means 26.
  • the main port means 26 is channeled to two separate vacuum supplies (not shown) so that the outer rows of vacuum ports 29 can be vented independently from the inner row 28.
  • the inventive transfer uses an arcuate stationary plate to produce a pinch cutoff.
  • This is analogous to the structure described in co-owned patent No. 4,828,195 except that the targeted perforation is isolated in part by means of vacuum ports 27.
  • These ports 27 hold the tail T (FIG. 3) of the just-finished log on the bedroll 13 so that severing takes place between the ports 27 and the pinch point 30 developed by the coaction of the mandrel 15 and the arcuate stationary plate 31.
  • the lay-on roll 12 is equipped with an annular groove 32 in its outer surface which accommodates the inlet end 31a of the stationary plate 31.
  • the inlet end 31a has a surface 31b facing the bedroll drum 13 which is essentially tangent with the outer surface 12a of the lay-on drum 12.
  • the pinching of the web causes a small amount of slack as at W1 to be formed between the lay-on roll 12 and the mandrel 15.
  • This slack web is immediately attracted to the bedroll 13 by the vacuum port means 26 and also directed to the bedroll 13 and away from the lay-on roll 12 by the centrifugal force of the web on the lay-on roll 12.
  • the vacuum port means 26 then pull the slack web W1 under the rolling mandrel 15.
  • FIG. 4 illustrates what happens in the enveloping of the mandrel 15 by the web a short time later than that depicted in FIG. 3.
  • W3 which is rearward in the direction of advance, i.e., upstream from the previously mentioned leading edge portion W2.
  • This leading edge portion W3 is now in the process of being folded under the mandrel 15 as at W4.
  • W5 the folded nature of the leading edge portion is seen more clearly and is designated W5.
  • This folded edge W5 is lifted and rolled by the rubbing action of the web leading edge portion W2 moving over it.
  • the vacuum port means 26 is arranged to enhance this tendency by allowing the web leading edge portion to expose the first row of ports 29a, hence allowing the vacuum therein as well as that in port 29b to decay prior to the vacuum in the ports 28. This, in turn, allows the web leading edge portion W3 to be attracted to the bedroll 13 while the folded leading edge portion W5 is being released. Once the folded leading edge portion W5 is raised off of the bedroll 13, it is trapped inside of the web leading edge portion W2 by virtue of the rolling of the mandrel 15.
  • the geometry of the arcuate stationary plate 31 is arranged to allow for the rapid buildup diameter during the first part of the winding cycle.
  • the gap 33 between the periphery of the bedroll 13 and the interior 31c of the stationary plate 31 gradually increases in proceeding from the upper inlet end where the mandrel 15 is being inserted until the outlet end 34 is reached.
  • the new log reaches the outlet end 34, it rolls off of the plate 31 and proceeds to wind between the first or upper winding drum 13 and the second or lower winding drum 17.
  • the remainder of the winding cycle generally follows that of a conventional surface winder in utilizing the rider roll 18, and inclined rolldown table 21.
  • the next mandrel is inserted for transfer as the cycle repeats.
  • the rider roll releases the finished log L''' which in turn rolls down an inclined exit table 21 to a roll strip conveyor generally designated 24.
  • This conveyor is similar to the roll strip conveyor on co-owned patent 3,071,259.
  • the gripper mechanism 22 lifts the mandrel 15 up onto the mandrel conveyor generally designated 35.
  • One or more arms are provided along the length of the mandrel in order to help support the mandrel while it is being raised to the conveyor 35.
  • the mandrel conveyor 35 then positions the mandrel to be received by the core inserter mechanism 14.
  • Either side frame 10a, 10b is advantageously equipped with control means for regulating the various steps and actions described herein.
  • advantages of the invention is the ability to operate a continuous running surface winder with recycled free mandrels and without the need for using adhesive or another means for adhering the web to the mandrel.
  • a further advantage is the novel use of vacuum to hold both the feeding web and the web leading edge portion on the bedroll 13 to accomplish an enveloping transfer. This is further advantageous, again, in the elimination of adhesive or other means for maintaining the web in contact with the mandrel.
  • the invention also is advantageous in that an extensible material such as rubber, plastic and the like can be used as the material for construction of the mandrel 15 so as to facilitate roll stripping.
  • an extensible material such as rubber, plastic and the like
  • longitudinal elongation caused by the stripping forces is accompanied by a reduction in radius.
  • the relationship of the two depends upon Poisson's ratio.
  • the compressive grip of the convolutely wound web on the mandrel is successfully reduced and overcome by the stripping force in combination with the elongation and reduction in radius.
  • Another advantageous function of the invention is the opportunity of using porting on the bedrolls to isolate one specific line of perforation so as to give an exact sheet count.
  • the use of the long stationary plate is advantageous to permit a significant build up in diameter of the log before rolling in to the three roll cradle winding nip.
